U i T T E S CASE HANGER.

Application flled August 4, 1922. Serial No.\5 79,642.

T0 aZZ whom it may concern:

Be it known that I, TVILLIAM C. FRASER, a citizen of the United States of America, and a resident of the city of Buffalo, county of Erie, and State of New York, have invented certain new and useful Case Hangers, of which the following is a full, clear, and exact description.

My invention relates in general to hangers and more particularly to a hanger for suspending cases in an electroplating bath.

As is well known, in electroplating baths, it is customary to suspend the mold-case by hooks which are carried by the hanger having bearing surfaces which contact with the surface of the mold. In such hangers the metallic hook for suspending the mold case is bent and formed after it is assembled in the hanger. Since these hooks require frequent renewal, this type of hanger is an expensive one to maintain. Furthermore, the operation of replaclng such a hook 1s a difiicult one, and cannot be done by the workmen in charge of the electroplating bath. This necessitates that a number of hooks be kept on hand to be used while others are being repaired.

The principal object of my invention has been to overcome the disadvantages above enumerated and to provide a case-hanger, the case-hook of which, with its insulating member, is easily separable from the hanger. By this arrangement the hooks may be easily formed by anyone, and a number of them kept on hand, so that a replacement of the casehook in my hanger is a very simple and inexpensive operation.

Another object has been to provide a hanger of this type, in which the case-hook shall be prevented from side movement, which would permit it to contact with the other parts of the hook carrying electric current.

The above objects and advantages have been accomplished by the device shown in the accompanying drawings, of which:

Fig. 1 is a side sectional elevation of my complete device, and is taken on line 11 of Fig. 2.

Fig. 2 is a front elevation of the device.

Fig. 3 is a fragmentary, plan, sectional view taken on line 3-3 of Fig. 1.

The hanger comprises a body part 5 which is provided at its upper end with a rodhook 6*, which designed to fit over the rod conducts electric cii'rrent to the meld.

This hook is provided with a suitable handle 7 whereby the device may be easily lifted. The body is preferably provided at its lower end with two outwardly extending arms 8 to the lower end of each of which is secured a contact block 9, which contacts with the mold carried by the case for conducting electric current to it.

The lower end of the body, at the point where the arms 8 are connected thereto, is provided. with an outwardly extending lip 10 in which is formed a semicircular recess 11. 12 is a clamp member, which has a semicircular recess 13 that registers with the recess 11. The clamp is preferably provided with a lower inwardly extending lug 14: which engages with the outer surface of the lip 10, and also with an upwardly extending arm 15, which contacts with the body 5. A bolt 16 passes through the arm 15 of the clamp member and also through the body 5, whereby the clamp member is securely held in position.

17 is the case-hook which is provided with a horizontal member 18 and two downwardly extending and upwardly bent arms 19 for engagement with the usual holes formed in the case-mold. A sleeve 20 of insulating material is centrally arranged upon the horizontal member 18 of the casebook 17. A metallic washer 21 is preferably arrnged at each end of the insulating sleeve 20 and soldered in place, whereby the hook 17 will be prevented from sliding within the sleeve but permitted to have free rotary motion therein. The outside diameter of the sleeve 20 is preferably the same as the diameter of the hole formed in the hanger by the recesses 11 and 13. The proportion of parts is such that when the clamp 12 is placed in position and the bolt 16 tightened, the sleeve 20 will be gripped in position, whereby its axial movement will be prevented.

From the foregoing, it will be clear that to replace the case-hook in my hanger is an extremely simple operation, which can be done by anyone. Since the hook is so easily separable a number of them may be kept on hand and broken or worn hooks may be quickly replaced without having to take the hanger out of service.

Obviously some modifications of the details herein shown and described may be made without departing from the spirit of my invention. or scope cf the appended claims; and I do not, therefore, wish to be limited to the exact embodiment herein shown and described.

Having thus described my invention, what I claim is:

1. A case hanger comprising; a body formed with a recess, a clamping member formed with a recess which register-s with the recess of the body, means for securing the clamping member to the body, and an insulated case hook detachably disposed within the recess of the body and the clamping member.

2. A case hanger comprising a body provided with an outwardly extending; lip in which is formed recess, a clamping member formed with a recess which registers with the recess of the body, means for securing the clamping member to the body, and an insulated case hook detachably disposed within the recess of the body and the. clamp member.

3. 'A- case hanger comprising a body formed with a recess, a clamping member formed with a recess which registers with the recess of the body, means for securing the clamping member to the body, a case hook, an insulating sleeve rotatably mounted upon the case hook, and means for preventing the axial movement of the hook within the sleeve. 7 r 4 l. In a case hanger, the combination with a body ttormed with means for contacting with the mold, and means for supporting the hanger, of an insulating case hook, and a clamping member for detachably securing the case hook to the body and extending upwardly from the hook.

5. In a case hanger, the combination with a body formed with means for contacting with the mold, and means for supporting the hanger. of an insulating case hook, mountedwithin a recess formed in the body, and a clamping member also formed with a recess which registers with a recess of the body whereby the case hook may be detachably secured in place.

In testimony whereof, I have hereunto signed my name. i 7' WILLIAM 0. raser.
